Experimental investigation of grinding temperature and burn in high speed deep camshaft grinding

Abstract

Camshaft grinding is more complex comparing with the ordinary cylindrical grinding. To improve grinding efficiency and quality, high speed deep grinding with CBN wheel has been shown great advantages. This paper presents an experimental investigation of grinding temperature and depth of maximum un-burn (DMUB) in high speed deep camshaft grinding. A series of experiments have been accomplished by CNC8325 NC camshaft grinder. The results show that the grinding temperature increases with the peripheral wheel speed rises from 60 m/s to 130 m/s. Grinding burn occurs when bigger depth of cutting is applied. The higher peripheral wheel speed has a positive effect on improving depth of maximum un-burn.
